UBD rotary heads can profit from the unique design of their rotary head, which allows for exceptionally even water distribution, assuring optimum surface coverage. They assure, therefore, very short washing cycles, using lower quantities of water, with a definite advantage in those applications where recycled water is not allowed as a washing medium, and the volumes sent to disposal must be kept to a minimum. UBD heads work using Teflon slide bearings floating at high speed over a thin water film, the only worn part being an easily replaceable Teflon washer. Only a fraction of the liquid energy is then used to power the washing head, while the high speed of the rotating disc instantly produces a loud of high-energy droplets all over the inside surface of the tank. The clever design of this device results in no maintenance at all being necessary. The straightforward design makes sanitizing quick and easy. Models with 3/4″, 1”, and 1-1/2” connections can also be provided with NPT thread: in this case, H can be slightly different.
Made without bearings, they are the version of the UBD range with a 1/4 ”BSP male thread. The rotor, completely in Teflon, reduces friction to a minimum, eliminating any lubrication need. Because of its small size, this head is ideal for the internal washing of small tanks with not too viscous residues.
Models with 1/4 ” BSP connections have Teflon rotors.
